以吗啡为阳性对照药物, 采用热板法进行实验。
5、 具体实验操作:
取小鼠 30〜40只, 雌雄各半, 体重在 18-23克之间。 首先, 分别 将小鼠置于 55.5Ό的热板上测试 2〜3次基础痛阈值, 基础痛阈值 5〜 30s为合格, 淘汰不合格的小鼠。 取 30只合格小鼠将其分为五组, 分 别为: 阴性对照组、 阳性对照组、 低剂量组、 中剂量组和高剂量组, 具体如下:
阴性对照组 直接测试基础痛阈值
阳性对照组 吗啡 0.2mg/ml 0.2ml
低剂量组 受试药物 lmg/ml 0.2ml
中剂量组 受试药物 2mg/ml 0.2ml
高剂量组 受试药物 4mg/ml 0.2ml 小鼠经颈部皮下注射测试样品溶液 (10mg/kg, 20mg/kg, 40mg/kg), 阳性对照组皮下注射吗啡 (2 mg /kg) , 1小时后各组小鼠分别测痛阈 值作为给药后痛阈值。 按下面的公式计算痛阈提高率- 处理后痛阈-平均基础痛阈 ―
痛國提局率%= 平均基础痛阈 χ ΐοο%
6、 部分化合物实验结果: 详见表 4 表 4
*表示 P值<0.05, **表示 P值<0.01
实施例 62
化合物 m-i5的药物依赖性实验
1、 初步耐药性研究:
用热板法测试, 小鼠灌服 ΙΠ-15 ( 60mg/kg) 产生的镇痛作用不为 纳洛酮(lmg/kg, ip)翻转。但吗啡及强痛定(盐酸布桂嗪, Fortanodyn) 产生的镇痛作用均被纳洛酮翻转。 小鼠连续 8 天, 每天灌服 111-15 ( 60mg/kg) , 每次给药后 15min用热板法测小鼠痛阀变化。 ΠΙ-15在 连续用药条件下痛阀未见减弱。 阳性对照药吗啡 (lOmg/kg, PO) 在给 药第二天后, 镇痛作用逐渐减弱, 呈现明显耐药性。 提示 111-15多次用 药后不显耐药性。
2、 初步成瘾性试验 (纳洛酮翻转试验) :
用小鼠跳跃及条件性位置偏爱试验,分别测试 111-15的身体依赖及 精神依赖作用。 小鼠于 2天内按递增剂量 (20-120mg/kg, PO)给予 111-15 七次剂量, 在最后一次剂量后 3小时, 再静脉注射纳洛酮 2mg/kg, 未 观察到小鼠出现跳跃反应, 而吗啡组小鼠则出现明显跳跃反应。 小鼠 每天灌服 ΙΠ-15 60mg/kg, 连续给药 6天后测试, 小鼠未出现条件性位 置偏爱, 而吗啡小鼠则出现明显条件位置偏爱。 结果提示, ΠΙ-15不同 于吗啡, 在多次用药后不产生成瘾性。 实施例 63
111-15的急性毒性初步实验:
用 Bliss法统计, 小鼠单次灌服 ΙΠ-15 的 LD5o为 452mg/kg。 大鼠 单次灌服 ΠΙ-15的 LD5。为 524mg/kg。 实施例 64
ΙΠ-15的细菌回复突变试验
菌种: 鼠沙门氏菌组氨酸营养缺陷突变株 TA97, TA98, TA1()0和 TA
结果: 实验包括 -S9和 + S9两个部分, 在无 S9测试系统中 TA98和 加 S9测试系统中 TA97 5000μ8/皿有抑菌作用。 其它剂量对所有菌株均 无抑菌作用, 生长背景良好。 所有测试剂量无论在无89或加 S9实验系 统中, 均未引起任何菌落回变数明显增加, Ames试验阴性。 上述结果表明, ΙΠ-15 具有明显镇痛作用, 口服吸收较好。 111-15 多次用药后不显耐药性, 药物依赖性潜力很低, Ames试验阴性, 治疗 指数较大, 具备作为一类新型非成瘾性镇痛剂研究开发的潜在价值。
